que: i have a test tomorrow in spanish 2 and my teacher didnt teach cleary the difference between the two.. please explain!|||tener ganas de means i have the desire to... tener que means i have to...|||"Tener ganas de" - means: "to want to" ...do something or "to have a desire to do somethin". literal translation: "to have want of". It's a colloquial expression not used everywhere. "Tener que" - means: to "have to" (...do something). Conjugation: Tengo ganas de ver una pelicula / I want to see a movie. Tengo que ver una pelicula / I have to see a movie. Tienes que ver una pelicula / You have to see a movie. And so on, hope this helps. Suerte!|||ganas come from ganar, which is to earn;to win i havent heard the expression tener ganas, but it would literally mean: to have to win/earn tener que means to have to.
